Well, there's that, but I still don't know much about other targets.
I mean, I looked over the keymaps and can avoid duplicates and
whatnot, but until you live with the actual physical object for a
while, you still don't really know how friendly it is to use. I'd
rather not futz with something I know nothing about. And anyway, at
worst, everything stays exactly the same for unaffected targets so I
don't see the downside here. Let experts in those targets pick and
choose how their keys ought to work.
Why not try to recruit some of those experts to get the keymap done now
then, rather than just hoping they'll come along later?
